Be vit known that I, EMIL H. Murrina citizen of the United States,residing,- at Saratoga, in the county of Hardin and State of Texas, haveinventedy certain new and useful Improvements in a `lVire-\VintliiigMachine, of which the following` is a specification. I p p Thisinvention relates to new and use-ful improvements in a wire win'dinp,`mach-ine.

One object ofthe` Ainvention is toprovide a wire winding machinespecially designed for the purpose of winding wire on a frame orperforated pipe in theV process of manufacturinglwell screens.- Y y iAnother object of the invention isA toA provide a machine of thecharacterdescribed whereby the screen wire may be wound on theperforated pipe, or screen frame, in the form of a helix, with itsturnsspaced a uniform-` distance apart. Y

A. further feature of the invent-ion resides in the provision of a wireWinding' machine whereby spacing` lugs, ofv 'uniform height may bethrown out from thewire Vas it passes through` the machine, and saidjlugs, being' formed ofuniformWheight, need not be cut down to produceevenness in heighu and their' galvanized coatingthus need not bedestroyed. 'A ,y

consists 1n an nna section of the screen wire, with the spacing;` y

lugs formed thereon; and,`

Figure 6 shows acrossA` section through adjacent turns of'thescreen'wireas wound on the pipe. i v

Referring now morehparticularlyf to the drawings,-wherein like numeralsofreference-designate similar parts in each ofthe ggures, the numeral 1designates the'body vlof the lathe, Thenumeralr 2 designates the lathecarriagewhich runs' upon the tracks 3, 3 forming part of the .lathebody.m` The perforated pipe 1, formingv the screenframe, is mounted inthe lathe, and is rotated fromthe lathe chuck (not shown) infthe wellknown manner. along, as winding` progresses. by means of the rotaryscrew shaft 5"whi`ch is rotated b v the lathe mechanism andwliichl isthreaded through the split, tappedfbearing' carried by the carriage.VThe pipe 4'. issupported on the rollers i', 7. These rollers aremounted on the bearing` rods 8, 8', `whose re`- spective ends Vareanchored to the upper ends of the respectivepairs of toggle linkslt), 9.The `lower endsof theselinlrs of therespective pairs, have bearings ona'` common bearing' rod 1t), carried bythe'lathe carriage. The rollers7, 7, may be adjusted, andthe pipe d' thuselevated or lowered' throughthe adjusting screws 11, 11 whiclrare attached attheir' upper ends tosleeves 12,12 on'the rods 8 8, and have screw connections with tapped'bearings 18, 13 carried by opposite sides of the lathe carriage. As thecarriage moves along, thepipe 41 is rotated andthe screen-wire 11isW'Ound, in a helix,` on said pipe. The wire passes through between theguide rollers 15, 15 which aremounted in the frame 16'. These rollersare spaced apartv to allow space for the wire and they will" usually betapered upwardly since the wire,` in `cross Asection` is usuallylteystone in shape. The wire is held between the feed rollers by meansof a U-shaped bridge 1.7, forming part of the frame-16, and disposedabove the wire. The wire`v moves along in the grooves of the guiderollers 18, 18, can ried'by the frame 16, being` held in said `groovesby the' pressure' roller 19' which presses against tlieupper'side of thewire'. The pressure" rollerisvertically adjustable 'so as toaccommodatewires Aof differentsizes.

It isnec'essa'rythat the wire be wound-under tension' and theV pressureroller 19"imparts the tension required` Mounted onthe frame 16 there isay die roller 20, and above it, the punchinpgvroller 21. Y Theserespective `rollers are clanipediu `on and rotate with thespindles22`andf23, which in turn rotate" on: the" sleeves 243 and` 25, mounted,rrespectively, ony the bearing rods 26 and 27. The spindles `have'theinter-nal annular oil chambersff and 29,1Whichj`s`ur- The carriage isdriven sov round the lsleevest 31116.25, and-from which lead the ports30 and 31. Oil is admitted into the oil chambers through the respectiveducts 32 and` 33, for lubricating the sleeve bearings. r1`his mechanismis suitably mounted inalframe consisting of the side members 34 and 35,which in turn is secured to the frame 16. The dierollerhas .any annulargroove 36 ot the same cross sectional contour as that lof the screenwire, and at its top thisA groove is widened on one side orming-anabruptannularshoulder 3'? which is set baclr'l'rom' the main groove the exactdistance the turns of the screen` wire are to be spaced apart. Thepunching roller ..3V carries a pluralityk of projecting radiatingpunches 3S whose points are V.aligned with the groove .36 Vso as tostrikethe wire between its longitudinal center and its edge toward theshoulder 37 This alignment is maintained by the annular rib 39 o't' onespindle which runs in an annular groove 40 of the other spindle. Y. y

' As before stated the wire isk pulled through between the rollers bytherotation ot' the pipef4, and the punches indent the top side of the wireand thereby throw o ut the spacer lugs 41, onone side. `The heightofthese lugsis determined by the annularshoulder 37 against whichtheyabutV as lthrown out. This ,shoulder not onlyi insures the uniformity inheight of the lugs, lout alsoA forms their crests with flat `faces42vwhich form seats for the ylugs againstthe adjacent-turns of thel wirein winding.` as Villustrated in Figure 6` j f As the wire winds on thepipe 4, the lugs of the turn being wound are 'forced up ,closelyagainstthe preceding turn of wire by means ot a pressure lroller 43which is rotatably mounted on `the lower end oil the spindle 44. Thisspindle depends from the anchor 45, which inV turn is secured to thet'ra-me 16. rlhis ilrame`16 is mounted to pivoton the vertical axisbvmeans o'lf the bearing'451I.v which is mountedon the vertical spindle"46.1,carried 'byJ the lathe carjiiage 2. The frame 16 is also mounted topivot on a horizontal axis lbyjmeans ot the horizontal bearing 47 whichis 'formed integrally with the bearing 45 by .the web 48. A spindle 49is fastened to thc frame 16 and has aV bearing ink said horizontalbearing 47. The outer end of the spindle 49 has a `for Yardly'extendingrod 50, pivoted thereto which works through a. bearing 51 carried by thecarriage 2. The outer end of this rod hasa head 52 and interposedbetween the head 52 and the bearing 51, and surroundingthe r0d'50 thereis a coil pressure spring 53.' This springl` operates to hold thepressure roller 43 yieldingly vaga-inst the wire as wound on the pipe.

The spacer lugs hold the turns of wire Asuitably spaced apart on thepipe, .thus providing a screening surface.

The end of the frame 16, opposite its pivotal supportk on'its horizontalbearing 47, hasan open bearing 54, and an adjusting rod 55 is anchoredto the' lathe carriage and stands up through said bearing 54 and itsupper end i's provided with a head 56. There is .a slidable collar 57which rests on the rame16 and through which the rod 55 slides'and a coilspring 56 surrounds said rod and is interposed between the headf andthecollar 57. This coil spring operates to hold the pressure rolleryieldingly against the pipe.

, It is to be noted that the carriage heretotore designated by thenumeral 2 has n. movable section 2, capable of adjustment relativegtothe restrot the carriage. This section2ot the carriage carries the splitbearing 6 through which the screw shaft 5 is threaded. l

The main body Vof the carriage 2 hasV aligned be'aringsf59, 59. throughwhich the Stays 60, 60 slide. These stays are attached to the section 2.There is a. rotary internallythreaded sleeve 61,'which has a swivelingconnect-ion with the main carriage 2` and this sleeve 61. is turnable`through the hand grips 62 carried'thereby. There` is c i anoutwardlyrthreaded rodv63 fastened at oneY end tothecarriage section2.',-and it is threaded through the sleeve 61.v Inasmuch as the frame 16is carried by the main body of the carriage-9 this frame and the windingmechanism carried thereby, may be adjusted relative to the work by theadjustment of thecarriage sections, relative to each other, through themechanism hereinbefore described, provided -for that purpose. j i It isto be furthernoted that the punching roller is adjustable relative tothe die roller, 'sof that the strokej of` the punches against the wirecan be casilyfcontrolled. This adjustment fean Abe accomplished byturning the bearing rod 27 which .is eccentric relativefto the' punchingroller. This rod may bereadily turned through the collar G4 which issplined on said rod, as shown in Figure 4. This adjustment is alsonecessary to facilitate ythe threading of thewire through between theserollers in beginning the work or winding.

1t is also to be noted that there is a shim (l'ietween ther die, roller2O and the opposing shoulder ofthe spindle Q2 on which it is mounted. Byvarying the thickness ol this shim, or thel number or' shims, the roller2O can be laterally adjusted and the point of contact of the. punches88relative to the edge of the wire, thus regulated.

That 1 claim is:

1. In afwirewinding machine, a die roller having a; peripheral grec-ve,.a punching roller spacedfron'i the die roller, projecting punches radiating from thejpuuching roller,

and alignedfwith said groove, spindles on lll) retraso? which aidrollers are mounted, said spindles having internal annular oil chambersprovided with inlet ducts, bearing sleeves on which the spindles aremounted, said sleeves having oil ports, hearing rods on which thesleeves are mounted, and a frame in which said rods are mounted` 2. In aWire Winding machine, a die roller having a peripheral groove, apun-ching roller spaced from the die roller, projecting punchesradiating from the punching roller and aligned Withsaid groove, spindleson which said rollers are mounted, bearing rods on which .said spindlesare mounted, a 'frame supporting said rods, one of said spindles havingan annular groove andan annular rib carried by the other spindle andrunning in said annular groove.

3. In a wire Winding machine, mechanism including a die roller having aperipheral groove, a punching roller spaced from the die roller,projecting punches radiating from the punching roller and aligned Withsaid groove, means permitting the adjustment of one of said rollers onits hearing to vary the position of said punches laterally with respectto said groove, means for adjusting one of said 'rollers toward and fromthe other roller, a carriage formed of two sections, for driving thesame, said mechanism being mount-ed on the other section, and means foradjusting .said sections toward and from each other.

In testimony whereof I have .signed my name to this speciiication.

EMIL H. MEYER.
